If you have no experience in the design and nothing seems to be working out, write the content, make a version of the webpage on Tilda and hire a designer for a limited period of time. A professional designer will quickly arrange the webpage, and you will cut the costs several-fold in comparison to ordering a website from scratch. If you are a designer, ask your friend designer to look at it and comment on what you got. A fresh look will always immediately give feedback.
Publishing the website. Connect the domain. For this you should list the address in the project settings, and indicate where the domain was purchased in the registrar, specify the IP in one line.
Don't forget about statistics. Sign up for
Google Analytics, get the code and add it in the settings.
Mind how your website will look like on search engines or social networks and fill in the name and description. Provide each page with a small photo, then when your page is shared it will be properly framed.
Testing. You made a website, now you need to get the first reviews. Show the website to your colleagues or friends, ask them what they think. Send the link to your customers and ask for their opinions.
